4. Here are the steps Tyler took to solve the equation Vx+3 = -5. Vx+3=-5
+ 3
x + 3 = 25
x= 22
a. Check Tyler's Is the equation true if x = 22? Explain or show your
reasoning.
b. What mistake did Tyler make?

vx=-5-3

Step-by-step explanation:

vx=,-8 kkk

you probably already have the answer but anyways it's b. 15.0

step-by-step explanation:

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
